초록

김치제조시 녹차의 첨가방법이 발효특성과 관능적 품질에 미치는 영향을 조사하기 위하여 1%의 녹차추출물를 함유하는 소금물로 절인 후 담근 김치(I), 절임배추를 1% 녹차추출 물에 일정시간 담금후 제조한 김치(II), 녹차 1%를 양념과 혼합하여 담근 김치(III)의 3가지 방법으로 김치를 제조한 후 1$0^{\circ}C$에서 숙성시키면서 pH, 산도, 균수, 색상 및 관능적 품질을 조사하였다. 대조구의 pH는 숙성중 I~III의 경우보다 낮아 녹차처리구가 숙성이 지연되었다. 산도의 경우도 pH와 역으로 pH의 결과와 일치하였다. 그러나 녹차처리방법에 따른 큰 차이는 보이지 않았다. 대조구의 총균수와 젖산균수는 각각 6.16~9.29 및 4.59~8.42 log cfu/mL로I~III의 5.40~8.38 및 4.99~8.07 log cfu/mL보다 높았다. 김치조직의 L*값은 I< II

This study was conducted to investigate the effect of addition methods of green tea on the fermentation characteristics of kimchi. Kimchis were prepared to 3 methods such as Chinese cabbage soaked in brine containing 1% of green tea extracts(Ⅰ), salted the cabbage soaked in water containing 1% of green tea extracts(II), salted the cabbage mixed with seasonings containing 1% of green tea extracts(Ⅲ), and fermented at l0$\^{C}$. pH of Ⅰ∼Ⅲ kimchis were higher than that of control kimchi during fermentation and its acidity showed the same tendency. Total microbe(5.40∼8.38 log cfu/mL) and the number of lactic acid bacteria(4.99∼8.07 log cfu/mL) in Ⅰ∼Ⅲ kimchis were lower than those of control kimchi(6.16∼9.29 and 4.59∼8.42 log cfu/mL). Lightness of kimchi tissue showed the order of Ⅰ<II<control<Ⅲ. Sour taste and fishy taste of Ⅰ∼Ⅲ kimchis were lower than that of control kimchi. Overall quality was best in II estimated by sensory evaluation and fermentation characteristics.
